The National Historic Preservation Act (NHPA) has a new location in United States Code!
On December 19, 2014, the NHPA shifted from title 16 to title 54 of U.S. Code. The bulk of the Act has not been altered, although some organizational changes have been made. In addition, with the new location for the NHPA in U.S. Code comes new citations for sections of the Act.
